Understanding the movement a device produces helps a clinical team prepare a practical assessment. DPA Med enables lower limb and trunk mobilisation in a supine position. This page explains the biomechanical findings without turning a movement observation into a promise of clinical benefit.
The 2021 prospective study included 30 healthy adults. It assessed pelvic and shoulder movement at frequencies from 0.5 to 1 Hz. Dissociation occurred at the tested frequencies. Within this protocol, 0.808 Hz produced the lowest between-participant variability, with pelvic movement comparable to walking in the transverse and frontal planes. [1]
Kinematics describes how body segments move. Similar movement alone does not establish that someone subsequently walks faster, walks further or experiences less pain. Assessing those benefits requires suitable clinical outcomes, follow-up and an appropriate comparison. The frequency studied should therefore not be presented as a universal prescription.
The DPA Med instructions for use describe passive and active mobilisation capabilities. An available device function must be distinguished from the outcome of a particular programme. An imposed movement alone does not establish muscle strengthening or motor learning. Exercise selection depends on professional assessment and compliance with the applicable instructions for use.
A DPA Med study informs the protocol it evaluates. General research on trunk control or rehabilitation may inform clinical reasoning, but does not prove the effectiveness of a particular device. A demonstration, video or ultrasound observation is not a comparative clinical trial. Likewise, an absence of reported signals does not establish safety.
This page provides no basis for claiming clinical superiority over an axial traction table. Comparing mobilisation mechanisms and comparing patient outcomes are different tasks. Nor does it justify promises of faster recovery, fall prevention or an individual sporting benefit.
A demonstration can help your team observe the movement, understand the settings and discuss setup, precautions and training. It does not predict an individual patient’s outcome. Tell us about your practice and objectives without sharing information that could identify a patient.
